Search for New Physics through the Observables of Semileptonic $B_{c}^{+} \to D^{*+} ℓ^{+} ℓ^{-}$ Decay

Zohaib Aarfi, Qazi Maaz Us Salam, Faisal Munir Bhutta +2

Motivated by the current flavor anomalies and the comparatively less explored nature of the $b \to d$ sector, we present a model-independent study of the rare semileptonic $B_c^{+}\…

Weak Annihilation Contribution to Angular Observables in $B_{c}^{+} \to D^{*+} ℓ^{+} ℓ^{-}$ Decays

Zohaib Aarfi, Qazi Maaz Us Salam, Ishtiaq Ahmed +2

We analyze the rare semileptonic decays $B_{c}^{+} \to D^{*+} (\to P_{1} P_{2}) ℓ^{+} ℓ^{-}$ , with $P_{1} P_{2} = D^{+} π^{0}$ or $D^{0} π^{+}$ , and $ℓ = μ, τ$ . We focus on the impact of weak…

Lepton polarization dependent angular observables and the polarization asymmetries in the four-fold $Λ_{b} \to Λ (\to N π) ℓ^{+} ℓ^{-}$ decay

Rana Khan, Faisal Munir Bhutta, Ishtiaq Ahmed +1

The rare decays mediated by flavor-changing neutral current processes, such as $b \to s ℓ^{+} ℓ^{-}$ , provide powerful probes of the Standard Model and potential windows into…

Investigating New Physics through the Observables of Semileptonic $B_{s} \to K^{*} (\to K π) μ^{+} μ^{-}$ Decay

Zohaib Aarfi, Qazi Maaz Us Salam, Ishtiaq Ahmed +3

The rare four-fold decay $B_{s} \to K^{*} (\to K π) μ^{+} μ^{-}$ , governed by the flavor-changing neutral current transition $b \to d μ^{+} μ^{-}$ , provides a sensitive probe for testing the Standa…

Reinvestigating the semileptonic $B \to D^{(*)} τ ν ˉ_{τ}$ decays in the model independent scenarios and leptoquark models

Zhuo-Ran Huang, Faisal Munir Bhutta, Nimra Farooq +2

In this work, we revisit the possible new physics (NP) solutions by analyzing the observables associated with $B \to D^{(*)} τ ν ˉ_{τ}$ decays. To explore the structure of new phys…

Angular observables of the four-fold $B \to K_{1} (1270, 1400) (\to V P) ℓ^{+} ℓ^{-}$ decays in and beyond the Standard Model

Faisal Munir Bhutta, Abdur Rehman, M. Jamil Aslam +2

Recent measurements of the lepton flavor universality ratios $R_{K}^{μ e}$ and $R_{K^{*}}^{μ e}$ in $B \to (K, K^{*}) μ^{+} μ^{-} (e^{+} e^{-})$ at LHCb align with the Stand…

New Physics in $b \to s ℓℓ$ anomalies and its implications for the complementary neutral current decays

Faisal Munir Bhutta, Zhuo-Ran Huang, Cai-Dian Lü +2

Search for New Physics Signals via Doubly Weak B Decays

Faisal Munir Bhutta, Cai Dian Lu

The doubly weak $b \to dd s ˉ$ and $b \to ss d ˉ$ processes are highly suppressed in the standard model that offer the unique opportunity to explore new physics signals. The…

New Physics Search in the Doubly Weak Decay $B^{0} \to K^{+} π^{-}$

Faisal Munir Bhutta, Ying Li, Cai-Dian Lü +1

The doubly weak transition $b \to dd s ˉ$ is highly suppressed in the standard model, which makes it a potential channel to explore new physics signals. We present a study of th…
